Paying $25 to $50 to appraise a ring is not worthwhile,
depending on whats the content of gold(in K) and how many gram in your ring
24K is pure gold, 18k, about 75%, many shops are paying about $30ish for a gram
of 18K.. East Indian jewellery pays more- about $34ish per gram...

So at $30ish per gram, its almost half the value of Friday's gold price of $1713.50,($55 a gram);I would say $35 to $40 a gram is fair price(to me)

Oliver The Cash Man should be able to give you a price on the spot withiout you paying for appraisal...
